Official forecasts from the Korea Meteorological Administration and supporting models project a minimum of 16°C overnight in the Incheon area on September 16 under clear skies, light easterly winds, and stable high pressure typical of mid-September transition conditions. This aligns with observed temperatures hovering near 16–18°C in early morning hours and historical climatology for the region, where daily lows rarely deviate sharply without incoming frontal systems. Trader consensus at 99.2% implied probability reflects the tight clustering of ensemble outputs and minimal model spread. A realistic challenge would require an unforecasted marine layer or rapid advection of cooler air, though current observations and short-range guidance show low likelihood of such shifts before resolution.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=rksi
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
